NAME

du − summarize disk usage

SYNOPSIS

du [ options ] [ name ...  ]

DESCRIPTION

Du gives the number of kilobytes contained in all files and, recursively, directories within each specified directory or file name. If you do not specify a name, du begins counting from ‘.’. 

Used without options, du generates counts for each directory only. 

Du counts a file that has two links to it only once. 

OPTIONS

−s Gives only the grand total of kilobytes. 

−a Generates an entry for each file.  Absence of either causes an entry to be generated for each directory only. 

SEE ALSO

df(1), quot(8)

BUGS

Non-directories given as arguments (not under −a option) are not listed. 
If there are too many distinct linked files, du counts the excess files multiply.
